I Application filed December ,4, 1903. Serial No. 183,741.

To all whom it may concern.-

Be' it known that I, THoMAs OPIE ORGAN, a

citizen of the United-States, and a resident of Philadelphia, in thecounty of Philadelphia and State of Pennsylvania, hav.e invented a newand improved Feed-VVater Heater and Purifier, of which the following isafull, clear, and exact description.

This invention relates to an apparatus for I define the actualscopethereof.

on the line 2 2 of Fig. 1. side elevation with parts in section on theline 3 3 of Fig. 1.. Fig. 4 is a central vertical section of theinvention on'the line 4 4 of Fig. 3. Fig. 5 is a horizontal section onthe line 5 5 of Fig. 1. Fig. 6 is a horizontal section on the line 6 6of Fig. 4. Fig. 7 is 'a detail section of the float for controlling thevwatersupply. Fig. 8 is an inner side elevation of the oil-collector andthe intake-limb of the water-overflow trap. Fig. 9 is a plan view of oneof the water-traysand Fig. 10 is an enlarged section of the water-inletvalve.

The apparatus comprises an exterior shell 15. which is here shown assquare in cross-section and which may be formed of any suitablematerialfor example, sheet metal riveted together, as shown. Within theshell at the lower portion thereof is a horizontally-extending partition16, here shown as arched upward and having a centrally-located pipe 17-passing upward therefrom. Extending through the pipe 17 is awater-downtake pipe 18, which passes below the partition 16 to a pointnear the bottom of the shell 15.

19 indicates a mass of filtering material held between two perforateWalls 20, and through this 'filterthetube 18 passes. l

21 indicates a gate which commands the lower end of the tube 18, and 22indicates asuitable means for operating said gate,-this means extendingto the outside of the shell, as will be understood.

- The partition 16 is spaced fromthe filter and forms thereby afiltered-water chamber 23, while the filter is spaced from the bottom ofthe shell and forms thereby a settling-chamber .2 1. Uptake-pipes 25pass from the filteredwater chamber 23 upward to an annular pipeheader26, and from this header or manifold 26 a connection 27 extends to theside of the shell 15. Said connection communicates with the feed-watersuction-pipe 28, which passes to the boiler'and is commanded by a valve29.

A hood 30 is mounted on the upper end of the tube 17 and extends downaround the sides of the same to form a water seal at the upper end ofthe downtake-pipe 18.

31 indicates a vent-pipe passing from the interior of the hood 30 upwardto a point above the maximum water-line, so as to vent the interior ofthe hood 30 as the water rises therein.

32 indicates the water-supply pipe, which has a filter-blow-out branch33 passing down to the pipe 28 and providedwith a valve 3 1,-

as shown. Inward from the branch 33 the pipe 32 has interposed betweentwo of its sections a valve for. controlling the waterflow, 35indicating the casing of said valve. The valve is shown in detail inFig. 10 and comprises a cylindrical cage 36, located in the case 35 andreceiving .a sliding plug 37. Below the plug 37 is a chamber 38, formedin the case 35, and in this chamber a piston 39 is located. V

40 indicates a spring tending to hold the plug 37 and piston 39 in theiruppermost position, during which the valve is closed, and

11 indicates a suitable means for adjusting the tension of saidspring.

Extending from the main passage in the case 35 is a port 42, which leadsto an elongated chamberf13, extending alongside of the chamber 38. Fromthe upper part of the chamber 43 a port 44 extends. and 45 indicates aport extending from the lower part of the chamber 43, both of theseports comm unieating with the chamber 38. A port 46 extends from thechamber 38 back into the main passage of the case at the side of theplug 37 and cage 36'opposite the side on which the port 42 is located.Operating in the chamber 43 is an auxiliary valve 47, which when in itsuppermost position closes the port 42 and which when moved downwardcloses communication between the end portions of the chamber 43. Whenthe parts are in the position shown in Fig. 10, the spring holds theplug 37 in active position, thus keeping the valve closed. When theauxiliary valve 47 moves downward into the chamber 43, it

opens the port 42, and in this way water may pass from the main passagethrough the port 42, the upper end of the chamber 43, and through theport 44 into the upper part of the chamber 38; but the auxiliary valve47 will cut off the port 45. The result of this operation is that thewater entering through the port 44 and bearing on the upper side of thepiston 39 will move said piston downward, which piston carries with itthe plug 37, and in this way a free passage through the water-valve isprovided. When the valve 47 is closed, the spring 40 returns the plug 37to the position shown in Fig. 10, and as the piston 39 moves upward thewater from the upper side of the piston-is forced out through thepassages 44. 43, 45, and 46. Said auxiliary valve 47 has a stem 48projecting downward from the case 35 and connected by a link 49 (seeFig. 3) with a lever 50. Said lever is fulcrumed on a stud 51, risingfrom a float-box 52, this box being attached to the right-hand side ofthe shell 15. 53 indicates a weight attached to the opposite end of thelever 50, and 54 indicates a floatrod which is connected with this leverat the side of the fulcrum opposite that on which the weight is located.The float-rod 54 extends into the box 52 and is there connected with thefloat 55. The rod 54, as shown in Fig. 7, is hollow. Its upper end isfitted with a plug 54, and said rod extends continuously through thefloat 55 and projects downward through the box 52, where the lower endof the rod is open. Said rod 54 is formed with an orifice or orifices54", located within the lower extremity of the float 55. By thisconstruction any liquid that may sweat through the float will be drawnoff and automatically discharged. The shell 15 is formed with orifices15, communicating, respectively, with the upper end and lower portionsof the box 52, (see Fig. 1,) these orifices serving to fill the box 52and to equalize the pressures within the box or tank 52, so as to avoidinterfering with the regular action of the float. 1t

rises and falls within the shell 15 and box 52 the float will respond tothese changes and automatically operate the water-inlet valve, and inthis manner the water is kept at the predetermined level.

The water-supply pipe 32 leads into the top of the shell 15 at thecenter thereof and projects downward therefrom, the extremity of thepipe being formed with notches 32, and at the end of the pipe abafi'le-plate 56 is located, (see Fig. 4,) this bal'lle-plate serving tocause the water to pass out horizontally from the supply-pipe 32. Belowthe discharge end of the pipe 32 are a number of trays 57. These traysare preferably four in number and arranged one above the other, theybeing supported by rods 58 passing from the pipeheader 26 to the top ofthe shell. Between the trays thimbles 59 are interposed. to hold thetrays spaced apart, and 60 indicates a tierod extending through thetrays and thimbles, as shown. Each tray, as shown in Figs. 4, 5, and 9,is formed of a bottom 57, strengthened by an annular band 57" and havingsegmental openings 57 formed therein. Around the edges of the bottom 57vertical flanges 57 extend. This gives each tray essentially the form ofa Maltese cross. The said trays are arranged with the openings 57" outof vertical alinement, so that the water overflowing from the sides ofone tray falls into the water-spaces of the other tray, and thus thewater falls in thin sheets from one tray to the other. lCxtendingthrough each water-compartment of each tray is a tube 57, these tubessurrounding openings in the bottoms of the trays and formingstean'i-passages and also forming water-overflow passages. The edges ofthe flanges 57 are preferably serrated, as shown best in Fig. 4, butthis is not regarded as essential.

61 indicates the steam-inlet pipe, which passes into the upper portionof the shell 15 at one side of the trays 57. Within the shell 15 at thedischarge end of the pipe 61 is an oil separator or extractor whichcomprises a plate 62, placed directly opposite the end of the steam-pipeand fastened to the oil-funnel 63 and to the sides of the shell by meansof brackets 62". (See Fig. 8.) Said plate 62 has its edges turned inwardto form flanges 62, (see Fig. 5,) which prevent the oil from runningover the vertical edges of the plate to cause the oil to pass down intothe oil-collecting funnel 63. Attached to the funnel 63 at each side ofthe plate 62 are additional eilthe flanges 62, to prevent the oil fromrunning off of the outer edges of the collecting-plates. All of saidcollecting-plates lead down to the oil-collecting funnel 63. Said platesare formed with smooth surfaces, which enable will be seen that as thelevel of the water 1 the oil to flow readily, and as the steam entersthe shell it contacts with theoil-oollecting plates, and in this mannerthe oil is-separated from the steam, which latter passes through thespaces between the several plates and. pervades the upper portion of theshell, as will be understood.

66 indicates an apron overhanging the oilcollector. H

The funnel 63 discharges into the uptake branch 67 of a water seal, thedowntake branch 68 of which communicates with the lower end of theuptake-branch and has at its upper end afunnel 69. (See Figs. 4v and 8.)Over said funnel is located an apron 70; This funnel 69 has itsupper endlying at the predetermined maximum water-level, and when; the waterrises above this level it flows into the funnel 69 and thence into thetrap. From the upper end of the uptake branch 67 of the trap a pipe 71passes, this pipe lying outside of the shell 15 and discharging into atank 72., Under the lower end of the pipe 71 a deflector '73 is 10-cated. within the tank 72. Said tankhas a balanced valve 74 commandingthe outlet therefrom, and said valve is actuated by a rod 75 and float76, located within the tank 72.

77 indicates a thumb-screw for opening the Valve 74 to blow throughthe'tank and also to keep the valve unseated'should the float becomewater-logged and refuse to unseat the valve 74, and 78'indicates a plugin the valvecasing for enabling the valve to be seated and adjusted;

From the valve 74 adischarge-pipe passes to the hot-well, sewer, orother place where the overflow is to be conducted. From the lowersettling-chamber 24twoblow-olf tubes 80 pass to a pipe 81, which in turnleads to the pipe 79. I v

82 indicates a valve for controlling the pipe 81. I r

The suction-pipe 28 is provided with a ventpipe 83, which extends upwardfrom the pipe 28 and into the shell 15, said pipe havinga shell 15, saidtrap discharging into the shell and having a horizontal sheet 88 locatedat its discharge end to spread. the water out into a thin sheet as it isdischarged, thus enabling this water readily and quickly to acquire thetemperature of the Water within the shell and.

preventing hammering due to difference in temperatures. V

86 indicates an air-vent pipewhich passes from a point slightly abovethe normal Water level Within the shell 15 upwardand outward into theatmosphere,this pipe being designed to carry off excess air from withinthe shell,

the steam rising tothe upper part of the shell and the air, beingheavier, dropping to the water-surface.

90 indicates a water gage for indicating the height of water within theshell 15. (See Fig.

1.) The front of the shell is provided with a door 91'to enable access,tobehad to the up per interior of the shelland with a door 92 .toenableaocess to be had to the filter.

93.indicates manholes for reaching the interior of other portions of theapparatus. In the operation of the invention the float v55:dropping willopen the valve 35 and allow the water to flow through the pipe 82 untilit reaches the predetermined level within the shell 15, whereupon thefloat closes the watervalve.

water. The steam entering through the pipe 61 passes through these filmsof water, and a The water flows into the trays and overflowsin themanner described, producing a great number of very thin sheets offalling more effective condensation takes place. The

oil fromthe steam is collected and falls into the funnel 63 andtrap-limb 67. The hood 30 forms a Waterseal at the upper end of the pipel8.and renders it impossible for any filteringmaterial. to enter thepipe, so that should any oil escape the oil-collecting devices .orreturn with the water from the heating system it-will floaton thesurface of the water above the. partition. 16 and be carried off throughthe traps 67 68. The chamber above the partition 16 forms the firstsettling-chain vber, and any impurities in the Water may be precipitatedto the partition 16. The water will then pass, into the hood .30 andthrough the pipe 18 to the lower settling chamber 24, the valve 21 beingnormally open. From the chamber. 24 the water will pass up through thefilter into the filtered-water chamber 23, after which the purifiedwater passes through the pipes 25 and the pipe-header 26 to thesuctionpipe 28, which carries the water off to the boileror other pointof consumption. The drip from the heating system passing in through thepipe 86 mingles with the water too IIO

in the first settling-chamber above the partition 16 and goesthrough'the above-described operation as a part thereof.

In order to blow off or clean the filter, the gate or valve 21 should beclosed as well as the valves 29 and 84. The valves 34' and 82 should beopened, so as to allow the water from the supply-pipe 32 to run backwardthrough the pipes 25 and through the filter and thence out through thepipes 80 and 81.,

It will be seen, therefore, that the gate 21 is closed only during theblowing-out operation, and it will be observed also that this blowingoutoperation affects in no manner the parts in the upper portion of thefilter.

In connection with this invention it will be observed that it,providesfor a maximum con.- densation of the exhauststeam and a high temperatureof the feed-water, due to the peculiar trays 57 and the manner in whichthe steam is brought into intimate association with the water flowingtherefrom. It will also be seen that two distinct settling-chambers areprovided, one in the space above the partition 16 and the other in thespace between the bottom of the shell and the filter. The uppersettling-chamber receives any oil that may possibly pass theoil-collecting device, any oil that may return with the water ofcondensation through the trap 87, and any floating substance that mightpass into theheater with the water. The oil and floating substances willbe carried off by the trap 67 68, and owing to the hood 30 and the waterseal formed thereby nothing but the water is allowed to pass into thedo'wntake-pipe 18. The water receives its final settling in the chamber24 before passing through the filter into the filtered-water chamber 23.By arranging the filter as in this apparatus a relatively largefiltering-surface is secured, thus more effectively removing theimpurities from the water. The chamber 23 is made large enough to storea considerable volume of water, so that a reserve is always on hand andmay at all times be drawn out through the tube 28, notwithstanding thatthe water may be considerably below its normal level in thesettling-chamber 16, and owing to this chamber and to the manifold tubes25 and header 26, through which the water must pass from the chamber tothe boiler, a means is provided for the reheating of the water, sincesaid manifold tubes and header are submerged in the heated water abovethe partition 16, and, finally, it will be observed that an effectivemeans is provided for washing or blowing out the filter and bottomsettling chamber 24 without in any way interfering with the other partsof the apparatus.

Various changes in the form, proportions, and minor details of myinvention may be resorted to at will without departing from the spiritand scope thereof. Hence I consider myself entitled to all suchvariations as may lie within the intent of my claims.
